This commit is just a stopgap measure (i.e. it fixes the symptoms but not the
real underlying cause) of this bug. For some reason, iter->size is nearly always
an "effectively zero but not truly zero" value. Hence, the envelope sizes would
get adjusted, but would be scaled to an impossibly small value (taken from
iter->size).
From my investigations so far, iter->size is mostly either set to (or left as)
0, except in a rare case when dealing with volume snapping, when the values
somehow get propagated there from various intermediate data points. But, that
almost never works either.
from Josh Wedlake (joshwedlake), who provided a reference script used to apply changes in ED_rollBoneToVector().
- Obvious bug fixed where Z-Up didnt work right.
- More align axis options to Recalculate Roll operator: X/Y/Z/View Axis & Negate.
- Axis Only option, ignore the axis direction, use shortest rotation to align bones.
ED_rollBoneToVector() changes:
- would give bad roll when the axis wasn't normalized or perpendicular to the bone.
some callers accounted for this but not all.
- option to align to the axis but not the direction.
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
Only source/blender/editors/ dir, should not give errors on different platforms
Only removing: UI_*.h, ED_*.h, WM_*.h, DNA_*.h, IMB_*.h, RNA_*.h, PIL_*.h
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:

Polyline, selection and a couple of others work. (note that polyline is shift-click because click is taken by 3d cursor. Needs a way to overwrite lower maps).
